Michael Rapaport was flying back to El Lay on Saturday morning on a United Airlines flight from Houston when a man on the flight apparently got up, walked to the front of the plane, and began trying to open the emergency door!

Witnesses confirm that it was Rapaport himself who sprung into action, physically restraining the man involved and preventing him from opening the door with the plane thousands of feet in the air at cruising altitude.

Apparently, Rapaport saw what was happening and immediately jumped from his seat, yelling

According to United officials, the FBI and airport authorities spoke to the man who tried to open the emergency door, and eventually released him — they say he was very, very confused and had been on the flight to go back home to Vietnam to visit his mother, who is ill.

Regardless, an emergency was averted by the quick-thinking Michael Rapaport.
